Answer:
Explanation:
2-bromopropane is the major product because the reaction mechanism involves the formation of the most stable carbocation intermediate. When hydrogen bromide reacts with propene, the hydrogen atom from HBr adds to the carbon atom of the double bond that has fewer hydrogen atoms attached, resulting in the formation of a carbocation intermediate. The intermediate can either form 1-bromopropane or 2-bromopropane depending on the position of the carbocation. The 2-bromopropane is the major product because the secondary carbocation formed in this case is more stable than the primary carbocation formed in the case of 1-bromopropane.
To test for an alkene, bromine water can be used. When an alkene reacts with bromine water, the bromine molecule adds across the double bond, forming a colorless dibromoalkane product. The mechanism for the reaction between hex-1-ene and bromine involves the formation of a cyclic bromonium ion intermediate, followed by the attack of water on the intermediate, resulting in the formation of the dibromoalkane product.
a) Addition polymerization is a process in which unsaturated monomers are joined together to form a polymer. The process involves breaking the double bond of the monomer and joining the monomers together to form a long-chain polymer. The process requires a catalyst to initiate the reaction.
b) The repeating unit of the polymer formed from the addition polymerization of chloroethene monomers is -CH2-CHCl-. This polymer is called polyvinyl chloride (PVC), and it has a wide range of uses, including pipes, electrical cables, and vinyl flooring.

______ is produced anytime current flows in a circuit, due to the collision between the flowing free electrons and the fixed atoms.
Heat is produced anytime current flows in a circuit, due to the collision between the flowing free electrons and the fixed atoms. When an electric current flows through a conductor, the free electrons move through the lattice of atoms.
As they move, they collide with the fixed atoms, causing the atoms to vibrate and transfer energy to neighboring atoms. This energy transfer increases the temperature of the conductor, resulting in the production of heat.
The amount of heat produced is directly proportional to the amount of current flowing through the conductor, the resistance of the conductor, and the time for which the current flows. This relationship is described by Joule's law, which states that the heat produced is equal to the product of the current, the resistance, and the time.
Mathematically, this can be expressed as H = I^2RT, where H is the heat produced, I is the current, R is the resistance, and T is the time. The collision between the flowing free electrons and the fixed atoms in a conductor leads to the production of heat, which is proportional to the current, resistance, and time for which the current flows.

Gaseous ethane (CH3CH3) reacts with gaseous oxygen gas (0₂) to produce gaseous carbon dioxide (CO₂) and gaseous water (H₂O). If 69.7 g of carbon
dioxide is produced from the reaction of 26.76 g of ethane and 169.4 g of oxygen gas, calculate the percent yield of carbon dioxide.
Round your answer to 3 significant figures.
Answer:
The balanced chemical equation for the reaction is:
C2H6 + 3O2 → 2CO2 + 3H2O
To calculate the theoretical yield of CO2, we need to use the given amount of ethane and oxygen gas to determine which reactant is limiting, and then use stoichiometry to calculate the amount of CO2 that should be produced.
First, we need to calculate the number of moles of ethane and oxygen gas used in the reaction:
moles of ethane = 26.76 g / 30.07 g/mol = 0.8908 mol
moles of oxygen gas = 169.4 g / 32.00 g/mol = 5.304 mol
Next, we need to determine which reactant is limiting by comparing the number of moles of each reactant to their stoichiometric coefficients in the balanced equation. The stoichiometric ratio of ethane to oxygen gas is 1:3, so every one mole of ethane requires three moles of oxygen gas. Therefore, the limiting reactant is ethane, because there are only 0.8908 moles of it, whereas there are 5.304 moles of oxygen gas.
Using the stoichiometry of the balanced equation, we can calculate the theoretical yield of CO2:
moles of CO2 = moles of ethane × (2 moles of CO2 / 1 mole of C2H6) = 0.8908 mol × 2 = 1.7816 mol
mass of CO2 = moles of CO2 × molar mass of CO2 = 1.7816 mol × 44.01 g/mol = 78.5 g
Now, we can calculate the percent yield of CO2:
percent yield = (actual yield / theoretical yield) × 100%
actual yield = 69.7 g
percent yield = (69.7 g / 78.5 g) × 100% = 88.7%
Therefore, the percent yield of CO2 is 88.7%.
A liquid has a volume of 40,0 mL and a mass of 45,0 g. Calculate the specific gravity of the liquid
The specific gravity of the liquid is 1.125.
What is the specific gravity of the liquid?The specific gravity of a substance is the ratio of its density to the density of water at a particular temperature.
Therefore, we need to calculate the density of the liquid and compare it to the density of water at the same temperature.
The formula for density is:
density = mass/volume
density of the liquid = 45.0 g / 40.0 mL = 1.125 g/mL
At 4 °C, the density of water is 1.000 g/mL.
Therefore, the specific gravity of the liquid is:
specific gravity = density of liquid / density of water = 1.125 g/mL / 1.000 g/mL = 1.125

The air trapped inside a 240 mL glass bottle has a pressure of 1.0 atm and a temperature of 25.0 °C. To determine the value of k for the air trapped inside the glass bottle before and after cooling to show that P equals kT, we need to use the ideal gas law equation, which states that PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature. When the bottle is put into the freezer, the temperature decreases from 25.0 °C to -35.0 °C and the pressure decreases from 1.0 atm to 0.80 atm. Therefore, we can calculate the value of k by plugging in the values of pressure and temperature into the equation: PV = nRT. By rearranging the equation and solving for k, we find that k = PV/nRT. Plugging in the values, we get k = (1.0 atm x 240 mL) / (n x 0.0821 atm•L/mol•K x (25.0°C - (-35.0°C)) = 0.2021. This means that the value of k for the air trapped inside the glass bottle before and after cooling is 0.2021, thus proving that P equals kT.

Which of the following molecules would be most favorable to undergo an E2 reaction rather than an SN2 reaction with NaOH
2-bromopropane molecules would be most favorable to undergo an E2 reaction rather than an SN2 reaction with NaOH. Here option B is the correct answer.
An E2 reaction occurs when a strong base removes a proton from a beta-carbon adjacent to a leaving group, leading to the formation of a double bond and the departure of the leaving group. An SN2 reaction, on the other hand, involves a nucleophile attacking the carbon bearing the leaving group while the leaving group departs.
The relative favorability of E2 and SN2 reactions depends on the strength of the nucleophile and the base, the steric hindrance around the carbon bearing the leaving group, and the nature of the leaving group.
In this case, NaOH is a strong base, and the molecule that is most favorable to undergo an E2 reaction is the one with the least steric hindrance around the carbon bearing the leaving group, which is 2-bromopropane. The other molecules have more steric hindrance around the carbon bearing the leaving group, making them less favorable to undergo E2 reactions.

For a certain series of reactions, if [OH−][HCO−3]/[CO2−3]=K1 and [OH−][H2CO3]/[HCO−3]=K2, what is the equilibrium constant expression for the overall reaction? Write the overall equilibrium equation.
Answer:
Explanation:
The overall equilibrium equation can be obtained by combining the two given equations:
H2CO3 + OH- → HCO3- + H2O (1)
HCO3- + OH- → CO32- + H2O (2)
Adding equations (1) and (2), we get:
H2CO3 + 2OH- → CO32- + 2H2O
Dividing the second equation by the first, we get:
[CO32-][H2O]/[HCO3-] = K2
Multiplying the above equation with the first equation, we get:
[H2CO3][CO32-][H2O]^2/[HCO3-] = K1*K2
Thus, the equilibrium constant expression for the overall reaction is:
[K] = [H2CO3][CO32-][H2O]^2/[HCO3-]
where [K] = K1*K2.
